BALL-JOIN'IED CLEANING DEVICE FOR GAS-RECEIVERS.

Specification of Letters Patent.

Application filed February 6, 1911. Serial No. 606,747.

To all whom it may concern:

Be it known that I, HUGO BOSENIUS, a subject of the King of Prussia, andresident of 12 Humboldtstrasse, Bochum, in Testphalia, in the Kingdom ofPrussia, Empire of Germany, have invented certain new and usefulImprovements in Ball-Jointed Cleaning Devices for Gas-Receivers; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My present invention relates to cleaningdevices such as are made use offor cleaning-out the trough-shaped gas-receivers usually employed in themanufacture of coke and gas. The cleaning-devices hitherto employed forthis purpose chiefly consisted of a ball-joint built into the cover ofthe receiver mounted on top of the retorts, and of a bar passing throughsaid ball-joint into the interior of said receiver. This kind ofcleaningdevices with the cover of the usually trough-shaped receivernecessitates, however, that for each cleaning-opening a cleaning-deviceis provided, which for larger plants causes a considerable outlay ofmoney.

To avoid these drawbacks is the object of my present invention, which isattained by building the ball, through which the cleaning-bar passes,not any more permanently into the cover of the receiver, but instead ofit into a loose plug or stopper capable of being inserted into any oneof the cleaningopenings of the receiver-cover after the plug whichusually closes such opening has been removed. In this manner it is madepossible to serve all the cleaning-openings by the aid of but onecleaning-device, which can be inserted into or removed from any one ofthese openings at a moments notice.

In the accompanying drawing :Figure 1 is a vertical sectional view of mynew cleaning-device. Fig. 2 is a similar view of a modification thereof.Fig. 3 is a plan-view of the cleaning-device illustrated in Fig. 1. Fig.4 is a cross-sectional view of the gasreceiver provided with my newcleaningdevice. Fig. 5 is a longitudinal section on a reduced scale,through the top of the gas receiver. Fig. 6 is a detail of one of theopenings showing it closed.

Each of the cleaning-openings a of the cover 6 of the gas-receiver c isin accordance with Fig. l encircled by a ring 03, the opening of whichforms in connection with the opening a a seat 6 for the plug f havingthe shape of a frustum of a cone. consists of the two divisions g and hunited by means of the screws 2' to form'a single rigid body andrecessed at their center to form a seat k for the middle zone of theball Z through which the bar m is passed. The sharp edges of the seat isare chamfered off at n and 0 respectively to permit on the one hand thegreatest freedom to the bar m and obtain on the other hand a seat iswhich not I only shall sustain the ball Z sufliciently but also preventthe escape of gas between said ball and its seat. The collar 70 on thebar m is provided for easily removing the plug f from thecleaning-opening'a, which is ac complished by drawing the bar upwarduntil said collar rests against the under-side of the ball Z and thustransmits through its intimate contact with said plug any pull exertedon the bar to said plug and removes the latter in this manner from itsseat.

To use the new cleaning-device it is only necessary to remove the commonplug a usually closing the cleaning-hole from its seat e and replace itby the plug f, which on account of its conic shape is pressed into theseat 6 sufficiently tight under the influence of the bar m to prevent anaccidental removal of the plug After the cleaningwork has beenaccomplished the plug f is removed by the aid of the bar m in the mannerexplained above, whereupon the cleaning-opening a is closed again by acommon plug.

The modification of my invention illustrated in Fig. 2 difiers from thecleaningdevice shown in Figs. 1, 3 and 4 as its conic seating-surfacedoes not extend from the bottom upward to the top, but is limited by aring-flange t partly formed by an annular extension of the lowerdivision 9 and partly by the upper division 7" of the plug 5. Bothdivisions are here united by means of the rivets u which of course mightbe replaced by screws, as shown in Fig. 1, if so desired. Thecleaning-opening a of the cover I) is here shaped to form a seat 41,wherein the plug 8, aided by the flange t, is sustained during thecleaning-operation. The ball 'w encircling the bar w is here seated inthe conic seat y of the lower plug-division g in such a manner that agas-tight closure is formed, whereas the upper division 1' of said plugapproaches the ball to only sufliciently The latter v 5 L In a device ofthe character describech v 1, a gas receiver havinga plurality ofcircular to prevent the latter from accidentally leav-. ing its seat 7The insertion of this device 7 into its seat and its removal therefromcoincides in every respect- With the man pulatlons descrlbed inconnection With 7 the cleaning-device"illustrated in Figs. 1 Band; 4;Both embodiments of my invention are alike in their mode of operationand efficiency. I I claim:

In a device of the character described, a gas receiverhaving a plurality of circular cleaning ports, bearings secured to thereplugs, an apertured ball rotatable the plug-socket, a cleaning barslidably engag- 'ing the ball aperture, and means on the bar forengaging the ball, whereby upon a Withdrawal the socketed plug togetherwith the ball is automatically removed from its seat.
